To aZlyw/zom it may concern.-

Be it 'known'that I, OLIVER S. LEAVITT, of Marcellus, in the county ofOnondaga and StateofNew York, have invented a new and useful Improvementin Machines for Drawing Hen1p,?FlaX,-and other F'brous Substances;

and l. doherebydeclare t at the following is.

a full and exactdescriptipn of the construetion and operatitfnlofthesanie, reference being hadto the annexed drawings, making av part ofthis specification, in which- Figure 1 is a longitudinal section, andFig. 2 a grqnnd plan,'the same letters referring to like parts in bothdrawings.

The frame is represented by a a a a. v

b (I represent the holding-rollers, and e 0 the drawing-rollers, eitherof which may be made whin ing-fluted andin the usual manner, hav-Ping-snclii' gnides before the holdingollers and such, afieondensing"apparatus after the drawing-rollers as may be desired, not necessaryhere to"--represent, The set of gill-bars o is propelled in thedirectionof the arrows by two chains, which pass over thewheels f and g,having-cogs which workbetween the joints of the chain. j

iionfnected, with the gill bar's e at each end are-arms, as atreaching,backto joints in lhechain, through which. pass pieces parallel to thegill-bars, by which the chains and bars:

are connected. The gilhpins attached to each barpenetrate the material,(hemp, flax, or other librons uQb't'S'iZZlHCG the slivers of which havebeen introduced by the holding-rollers!) (Z afterfithey pass round tothe top of the wheel j resting upon the slide it, which is madeto extendlbrward toward the drawing-rollers c c as ifar as it is desired to havethe pins remain in the material. vJust as the barhas passed the "endof'the guide t, (represented bythe' dotted line-at IO, Fig. 1,)a"piece,'w attached to .the -'piecem,.is brought down upon the gill-bar,or

upon one or bothjo'f its arms by the action of the crank q uponth'eshaft 1-, and immediately connected-with'the pitman 1). The bar, as atIt, turns as'upon. a; hinge, the joint being at y". Onv the outside ofthe chain, at oneend of the bars, a pieceis' attached to each bar havinga notch cut out of itsedge, as at z z z z, so that a point or dog ismade to project, as at Near the wheel 9 is a piece, 3', firmly fast-hened in such a manner that the point i must strike against it, theeffectof which is to do "press still more thc'bar, as at 7;, bringing itround, so as to be in the right position to move back underneath uponthe guide 8 s, which keeps the bars in position until they pass aroundthe wheel f andnntil the gill-pins connected with them enter thematerial. The action of the crank q as it rises moves the lover- I).with which it'isconnected at d, which works upon a fu'lcru-ni at c anddepresses the two rods a and a", the eiie'ct of which is to make thepins" enter the material to be drawn effect;

.nally, being raised by the descending motion of the crank q in time toclear-the pins as they pass forward toward'the drawing-rollersc c.

Thes'haft 1', upon which the cranks-"are, must make as many morerevolutions than the shaft upon which the wheel 5 is placed as there arecogs npon' 7, so as to depress each bar at the proper time, andalso todepress the rods 0, and. a once for each bar as it passes beneath them,which may contain one or more rows of pins, as may be desired. nectcdwith the wheel-XV, placed on the shaft 0 with the wheels f, onwhich thechains rnn,

should be such as will correspond with the motion of said wheels f andg. If g has four cogs, as in this case, and the wheel'f twelve,

ithe wheel XVshonld be three times the diam- --'-ter of the wheel-W,which is'connected on the same shalhor on shafts oft-he same speed withthe wheels 9. A pinion, is placed on the shaft of-the drawing-roller c,actingnpon the intermediate wheel \V'", which drives .\\/'upon thecrank-shaft 9-, and also W npon'the shaft containing i "anew. Theintermediate wheel \l/ connects fland \V, and the intermediate wheel\vflxrnnningon the stud .5, 'con nccts thejwheel \V- on the shaft with lpensing with the shaft, which runs through 1111- der thegill-bars'andinside the chains,- and the top rollers may be geared withthe lower onesfor be made to run by their traction thereto, increasedbysprings, weights, or 1evers, as may be desired Thegill bars may be The'carin 0011-,
